I have the same problem! When on the ground taxiing, taking off or landing it's a real immersion killer.
Reducing the graphic settings did not improve this issue.
Maybe it has to do with the graphic card drivers. I'm using the latest 310.70 WHQL from Nvidia. But this could be easily confirmed by other forum members, that might not have the problem, using the same drivers.
I was also suspecting, that I might have set up my system sub-optimal somehow, maybe contributing to those kinda errors. My computer specs are okay, but I put it together myself for the first time, so maybe I missed important things to setup propperly in BIOS or Windows. Not sure.
It's really frustrating to see that it works so well for others.
Soeren here for example doesn't seem to have the issue (Skip to 03:25 min and/or 22:05 min)
Thanks justme262 for the tip. I'll try it, although it sounds like it's not completely curing the problem, just making it more bareable.
Still keeping my fingers crossed for a solution!
